GENERATING APPARATUS.

Specification of Letters Patent. Patented Aug; 18, 1914;

Application filed July 14, 1913. Serial No. 778,971. i

in which the parts are kept efi'ectively cleaned of carbon. deposits, thus allowing heavy hydro-carbon liquids to be used with the same effectiveness as the lighter liquids,

as gasolene, are used in the ordinary constuctions. i

To this end my invention includes means for passing themain body of liquid hydrocarbon being used in the apparatus, through the generating parts at predetermined times to cause a thorough cleaning of the same.

I My features of invention while shown applied to a stove and light are equally .Well applicable to other analogousconstructions, where a generating burneris used as blow torches, etc.

In the accompanying drawing forming partof this specification, Figure 1 is a side elevation, broken away, of a stove and light embodying my features of invention; Fig.

2 is a front elevation of thesame broken away; Fig. 3 is a detail of a generator shown partly in section; and Fig. 4 is a section on line 02- 02 of Fig. 3.

Referring to the drawings, A represents the framework of a stove.

B represents burners of suitable construef tion supported upon the ends of branch gas pipes 2, each pipe at its connection with the burner being provided with a suitable controlling valve 3. The gas pipes 2 are connected through the generator C with a pipe l leading from the bottom of the oil reser- .voir D. A controlling valve 5, as shown, is arranged in connection with the pipe 4 a short distance from the generator. The generator, as shown particularly in Fig. 3, includes a central mixing tube 6 open at its bottom to the outer air, a jet orifice 7 being formed in the generator below the bottom of the mixing tube, a, needle valve 8 having screw threaded support in connection with the et orifice.

The generator chamber 9 is connected by a downwardly and laterally extending (1011-. duit l0w1th a second generating chamber 11. extending around the mixing tube below the generatingchamber .9. The lower generating chamber 11 is connected at its lower side by a conduit 12 with the jet orifice, the conduit 1 2 extendingpast the jet orificeto a.

tube 13 connected with the bottom of a filling tank El supported upon the rear of the stove. The inlet tube 4; is preferably filled with loose parts 14, as shot, for the purpose of pulverizing the hard carbon in the fluid supply. i

As shown, the mixing tube extends some distance above the generator 9, the generator being formed, with; an;outer open top tube 15.surroundingithe upper end of the mixing tube and spaced therefrom. Fitted over the outer tube 15 is a hood lfilwhich connects the pipes 2,1eading to the burners, and which hood 1siornied-w1th a (lOWIlwl wardly projecting portion 18.;above themix ing tube for the purpose .of dellecting the generated ga downwardly between the mix ing tube and outertube 15 to the sub-flame openings 19. The conduit 12 leading from the bottom of thegenerator is formed below F the pipe 13, with a closingqvalve 20. l

The supply tank D, as shown, is prefers 1 ably formed with; a gage 2].. to indicateithe amount ofyiliquiditherem. and wlth an air inlet tube 22 through, which air .may be pumped to allow air pressure to be kept upon. the contained hydro-carbon The air: inlet tube 22has a suitable closingvalveI23, and on the inner side ofithe valve an indi-.

cator 24: to show the air pressure. The filling tank is supplied. with an inlet open ng closed by a suitable cap 25. a j I show, in connection with my stove, a suitable mantle burner F supported upon a generator corresponding in. construction to the generator C except that in connection with the mantle burner I show one generating chamber surrounding the mixing tube instead of two. The mantle burner F is supported upon a pipe 30 extending down wardly through the top of the reservoir D i and substantially to the bottom thereof. The pipe 30 is shown provided with a suitable closing valve 26.

In. use, the liquid hydro-carbon, is supplied through the tank E. With the valves 5 and 20 open, the liquid will pass by grav 2:5: passages of the generator.

ity from thetankE through the generator and pipe 4i to the tank D, causing a flushing out and cleaning of the generator. Atter the tank E is emptied through the genera 5 tor to the supply tank D, the valve QO-Will be closed and remain closed during the proc ess of generating thegasi The supply tank Dbeing fill'ed inthe manner set forth, air can be pumped upon the-liquidwithin the tank through thelpipe 22 to maintain the requisite pressure upon the hydro-carbon liquid and'cause it to be properly t'edtothegenerator. After the use of therangeis completed and the gas turned oil, the -open-' ing-of the valve Withthe valye 5'open will cause the hydro-carbon liquid Within thesupply tank Dto be forced by the'coms' pressedair above it through the pipe l, generator and pipe 16'- to thefilling tank E.- 2 0:- The passing of the cold liquid back through the generator tothe filling tank will immediately cool thegenerator, cleaning the same and preventing the-ordinary boiling down and depositing of hard carbon in the Similarly the opening of the corresponding valve 20' in connection Withthe burner F'Will allow the cool liquid to flow baekathroug-h the generator: of the light F' to thefilling tank E.

-:T'hecap 25' of the filling tank is looseenough so that the compressed air passing" bacln from the supply tan-k Will escape from I the filling- I tank. Thus the i hydroecarb'on CO'OllIlg-i After the use, or the range is completed and the liquid-hydro-carbon forced} baclninto the filling tank, it-Will, as stated, immediately run-backi to thesupply tank 451; through the: generator, so that--Wh'en it 'is desired ii 130:. again use the range-it" is only necessary to-close the Valve 20 and pump air upon the liquid hydro-carbon in the supply tank.

My features of invention are equally applicable to generators for the purpose vshown and described or to generators used for kindred purposes as blow torches.

I I claim as my invention: 1. A liquid hydro-carbon generating system of the class described comprising a generator and burner, a filling tank, a supply tank, conduits connecting said" tanks through the generating chamber whereby to establish communication between said supply tank and filling tank through said generator, and means for forcing the' contents of? one'ofsaidtanks to'theoth er of said tanks-through said generator.

2. A liquid hydro-carbon generating sys tem of the class described comprislnga generator and burner, a filling tank, a su'ppl yu tanks through the generating chamber--wherebyto establish communication between said tank, conduits "connecting said supply tank and filling tankthrough said generator, and 'means permitting air tobe-- compressed Within said supply tank upon contained liquid hydrocarbon to force; the
